Cisco Systems aironet cb21ag User Manual

Your hardware or software token password

All necessary infrastructure devices (such as access points, servers, gateways, user databases, etc.) 
must be properly configured for any authentication type you plan to enable on the client.

The following information from your system administrator:

The logical name for your workstation (also referred to as client name)

The protocols necessary to bind to the client adapter, such as TCP/IP

The case-sensitive service set identifier (SSID) for your RF network

If your network setup does not include a DHCP server, the IP address, subnet mask, and default 
gateway address of your computer

The wired equivalent privacy (WEP) keys of the access points with which your client adapter 
will communicate, if your wireless network uses static WEP for security

The username and password for your network account

Protected access credentials (PAC) file if your wireless network uses EAP-FAST authentication 
with manual PAC provisioning

This section discusses the site requirements for both infrastructure and client devices.

Because of differences in component configuration, placement, and physical environment, every 
network application is a unique installation. Therefore, before you install any wireless infrastructure 
devices (such as access points, bridges, and base stations, which connect your client adapters to a wired 
LAN), a site survey must be performed to determine the optimum placement of these devices to 
maximize range, coverage, and network performance.

Infrastructure devices are installed and initially configured prior to client devices.

Because the client adapter is a radio device, it is susceptible to RF obstructions and common sources of 
interference that can reduce throughput and range. Follow these guidelines to ensure the best possible 
performance:

Install the client adapter in an area where large steel structures such as shelving units, bookcases, 
and filing cabinets will not obstruct radio signals to and from the client adapter.

Install the client adapter away from microwave ovens. Microwave ovens operate on the same 
frequency as the client adapter and can cause signal interference.
